I get these calls all the time too, on my cell phone no less. My auto warranty is about to expire blah blah. I call back and get this retarded speech impediment about the phone is no longer in service. WTF!
I too received a call from the same number, and when I called back it was an out of service recording which as someone else said it wasn't a real out of service recording. I have received this call numerous times about our car warranty. It's BS! Could be an identity theft scam. I'm going to block this number.
The recorded message (about extending car warrenty) sounds just like the one that kept coming from 1-305-267-9714 in August and early Sept. I have 2 phone lines and I get a call on each one almost every day. All my numbers have been on the DNC for several years. I do not know what the scam is, but apparently whenever they are caught "phone spamming" they just get a new number.
